Application filed October 21,

To all whom, it may concern:

Be it known that we, J AMES CRACROFT HALLER and ROBERT HOPE MAOHELL,both of Corporation Chambers, Dewsbury, in the county of York, England,have made a new or Improved Pipe-Joint, of which the following is aspecification.

This invention relates to joints of earthenware pipes and the like, theprincipal object thereof being to produce a water-tight joint at a smallcost in material and labor.

In the accompanying drawings, Figure 1 is a vertical ection, and Fig. 2is a section taken on the line A B of Fig. 1, of a joint con structedaccording to our invention.

The socket a is provided with an annular groove 1) and a pouring hole orholes 0 at the top. The spigot (Z has a smaller groove 6 in the shouldercorresponding at its outer edge with the groove 1) of the socket, aportionfof the extremity of the spigot being reduced to the thicknessand diameter of the inner rim 9 of the socket, so that the annular spacebe tween this portion f and the overlapping portion it of the socketshall correspond to the width of the groove l). Abeadt' on the spigot atthe invert preserves the alinement.

A flexible rod 76, Fig. 2, of cane, whalebone, or other suitablematerial, is inserted into the pouring-hole c and pushed along thegroove 6, traveling around the same until its forward end m againappears at the pouring-hole, and can be withdrawn therefrom, while atthe other end n of the rod 7c a strip 79 of canvas or other material isfastened. As the rod is withdrawn the canvas is pulled into thegroove 1) and forms a ring around the pipe-joint, as shown in Fig. 1.

The canvas p may be provided at the end or ends thereof with a clasp orbuckle or with copper or other wires for fastening, so that the ends ofthe strip of canvas can now be fastened together. Cement is then runinto the grooves through the pouring-hole c, the can- Speeification ofLetters Patent.

vas p preventing the escape of any cement into the interior of the pipe.A temporary outer strip 1" of canvas or leather may encircle the socketand shoulder-joint during the pouring in order to prevent any of thecement from escaping outward.

The joint made as above described can be finished while liquid stands inthe pipes, has a,

double seal, and by means of the rim-bead insures perfect alinement andtrue invert, While requiring no clay or other material except the cementand canvas.

We claim-- 1. A joint for earthenware and like pipes, comprising anannular groove in the butt of the socket, an annular groove in thespigot, a head on the spigot at the invert, a reduced end on the spigotcorresponding in thickness and diameter to the rim on the butt formed bysaid groove said reduced end forming a shoulder with which the end ofthe socket engages, a flexible strip surrounding the joint made by theend of the socket with the shoulder, and a cement filling, as set forth.

2. A joint for earthenware and like pipes. comprising a groove in thebutt of the socket, a shoulder on the end of the spigot a groove in theshoulder of the spigot, a bead on the spigot at the invert a reduced endon said spigot corresponding in thickness and diame ter to the rim onthe butt formed by said groove a flexible strip surrounding the jointmade thereby, securing means for said strip, a flexible stripsurrounding the joint made by the end of the socket with the shoulder,and a cement filling, as set forth.

In witness whereof we have hereunto set our hands in the presence of twowitnesses.
